Check back here often for more local event updates from USDA-ARS Pendleton, Oregon.
- The Liaison Committee of the Pendleton Agricultural Research Centers will meet in the center conference room on February 10, 2015.
- Dan Long will provide an illustrated talk that features the Cooperator of the Year at the Umatilla County Soil and Water Conservation District annual meeting on February 18, 2015.

- Stewart Wuest and Tami Johlke are analyzing data on the effect of delayed and reduced tillage on the amount of water stored by summer fallow. The data were collected over the past three summers, and it will take at least three months of concentrated effort to analyze the data.
- Hero Gollany is revising an invited review manuscript on Biogeochemical Research Priorities for Sustainable Biofuel and Bioenergy Feedstock Production in the Americas for a Special Issue of Environmental Management Journal.
- Dan Long, John McCallum, John Sulik, Aron Boettcher, and Hayley Peters-Contesse attended the Direct Seed and Oilseed Conference on January 20-22, 2015, and presented two illustrated talks and two poster presentations on their oilseed research. Aron Boettcher and Hayley Peters-Contesse are shown above with their poster presentation.
- Dan Long is preparing a manuscript describing the results of a study of the economic feasibility of segregating grain by protein concentration.
- A manuscript, of Dan Long's, describing the results of a study of profitability of terrain-based, variable-rate nitrogen application on spring wheat was accepted for publication in Agronomy Journal.
- Stewart Wuest attended part of the Oilseeds/Direct Seed Conference in Kennewick, WA. In addition to meeting with collaborators to plan a research proposal, it was a chance to find out what other researchers are learning about soil acidification in the Pacific Northwest.
- Dan Long applied to the FAA and was able to register the unmanned aerial system (UAV) that has been used by USDA-ARS in remote sensing research. The new registration number that was reserved for the aircraft is N56YU.
- Aron Boettcher is preparing for establishing two field experiments with oilseed. One will compare heat resistance and drought tolerance among different oilseed species and a second will compare different crop rotations comprised of cereal oilseed crops.
- Stewart Wuest presented information on efficient water storage, surface residue, and soil organic matter at the annual Conservation District winter meeting for growers in Dayton, WA.
- Hayley Peters-Contesse is compiling a database for life cycle assessment and carbon footprinting of the crop rotation study. She has been able to compile an exhaustive database and is almost ready to start conducting an environmental analysis of each cropping system.
- John Sulik submitted a manuscript to the International Journal of Remote Sensing. The paper describes how remote sensing can be used to measure flower density in canola and assess reproductive capacity and yield.
- John McCallum is working with Stewart Wuest and Tami Johlke on a study of the soil moisture requirements for seed germination of different species of oilseed.

John Williams, Stewart Wuest and Kate Reardon hosted a booth at the annual Explore Career Fair November 4th. The career fair was attended by approximately 1000 youth and community members.
- On December 16-17, 2014, Ron Rickman, USDA-ARS Emeritus Faculty (retired), and Tami Johlke, USDA-ARS Biological Research Technician presented “Wheat Development and Growth” at the Wheat Academy in Pullman WA. This event was sponsored by the Wheat and Small Grains Extension Department of Washington State University.
Hero Gollany monitors greenhouse gas (GHG) emissions in the long-term no-till wheat-fallow, wheat-pea (LTE NT), and conventional tillage experiments (LTE CT) to estimate emissions of carbon dioxide and nitrous oxide and determine the global warming potential of each cropping system. Wayne Polumsky (right) injects soil atmosphere gas into a collection vial. Joe St. Claire (left) collects soil atmosphere gases from a gas chamber in the long-term no-till plots for GHG determination.
- John Sulik and Dan Long are preparing a manuscript entitled “A Spectral Index for Reproductive Growth of Vegetation” for publication in a major remote sensing journal. This article describes work on a new spectral index that may be useful for monitoring crop growth and estimating within-field yield potential during flowering of various field crops.
Stewart Wuest and Tami Johlke continue to monitor the gain and loss of water from lysimeters, but this may be the last time this winter. The lysimeters allow us to compare different soil surface conditions, such as the amount of tillage and residue cover. It appears that evaporation after a rain and evaporation during a dry summer are very different processes.
- Aron Boettcher, Dan Long, and OSU weed scientist Judit Barroso are establishing experimental protocols for measuring the effect of weeds on grain yields in the cereal-oilseed rotation study. Judit and Dan are writing a proposal that will seek funding for identifying the impact of oilseed rotations on weed communities.
Joe St. Claire uses a bar code scanner to obtain a soil weight measurement from a platform balance. The measurement is transmitted via a wireless connection to a centralized data storage and retrieval system that is accessed over the Internet. This “Cloud Computing” approach allows for simultaneous data sharing with multiple users rather than waiting for the data to be saved and emailed.
- Stewart Wuest presented research findings on building soil organic matter and how to improve soil performance at the December 2014 conference, Building Soils for Better Crops, Moses Lake, WA.
Wayne Polumsky obtains a small sample of gas from agricultural soils using a static chamber and syringe. Samples are being taken each week to determine changes in emissions of gas over time. The method is used to estimate contributions of agricultural practices to the greenhouse effect.
- Janaina de Moura Oliveira returned home to Goias, Brazil after an eight month stay in Pendleton. During this time, she trained and worked with Hero Gollany on developing a data-base for the crop-livestock integration system and simulating several management scenarios using a soil carbon model to predict the best management for carbon storage in Brazilian soils.
Kate Reardon and Hayley Peter-Contesse are analyzing soil samples from the biofuel systems trial for microbial ammonia oxidation activity.
- Aron Boettcher is completing a water balance analysis summarizing the consumptive water use of different crops in the 2014 cereal-oilseed rotation study west of Pendleton. Aron and John McCallum are creating posters that will present the results of field oilseed research at the Direct Seed and Oilseed Conference in Richland, WA on 22 January 2015.
